Abstract (en)
In a storage medium such as a DVD+R or DVD+RW disc having a plurality of recording layers, the maximum address (i.e., the maximum physical sector number of a layer) of a user-data-recordable region (data zone) in each recording layer is recorded as physical format information in a wobbling groove. Based on the information, a recording/reproducing apparatus checks the maximum address of a data zone in each recording layer.
The medium has recording layers to which data is recordable. Wobbling grooves are pre-formed in relation to the recording layers as recording tracks in accordance with addresses and physical format information. The physical format information includes information of a maximum position at which user data is recordable in each recording layer. One of the recording layers has a data zone in which the user data is recorded. Independent claims are also included for the following: (a) a recording/reproducing apparatus having a storage medium (b) a recording/reproducing method for a storage medium.
